摘 要： Wear resulting from particle intrusion is one of the principal causes of failure in rolling bearings. Furthermore, studies have demonstrated that surface texturing can improve the frictional properties of such bearings. To evaluate the damage resistance of textured surfaces, four typical contaminants with varying physical properties were added to the textured bearings. The tribological and dynamic properties of the textured bearings under lubricant-contaminated conditions were investigated, and the mechanism of wear reduction on textured surfaces under rolling conditions was discussed. Test results indicate that textured surfaces have a significant impact on wear reduction for brittle and plastic materials that are not magnetic. However, the reduction effect is not significant for bearings contaminated with magnetic materials.

颗粒侵入引起的磨损是滚动轴承失效的主要原因之一。此外，研究表明，表面纹理化可以改善此类轴承的摩擦性能。为了评估纹理表面的抗损能力，将四种具有不同物理特性的典型污染物添加到纹理轴承中。研究了在润滑油污染条件下纹理轴承的摩擦学和动态特性，并探讨了纹理表面在滚动工况下减小磨损的机制。测试结果表明，对于非磁性脆性及塑性材料，纹理表面对减小磨损具有显著影响； 然而，对于被磁性材料污染的轴承，其减损效果并不明显。
